What's On It

What is in your protein powder, counted from its ingredient list

The ingredient lists of 30 protein powders sold in the US, read from each brand's label or product page and counted the same way. Facts only: no rankings, no ads and no brand photos. We explain what is on the label. We don't say whether an ingredient or product is good or bad.

How the 30 powders are counted

Every item separated by a comma in the list counts as one. A blend with its parts in brackets counts as one too. Read the full rule.
